CHAIR-SEAT.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed September 10, 1915. Serial N 0. 49,894.

To all 10 ham it may concern:

Be it known that we, FRANK H. HURD and EVERETT J. HEULE, citizens of the United States, and residents of IVabasha, in the county of Wabasha and State of Minnesota, and Superior, in the county of Douglas and State of Wisconsin, respectively, have invented a new and useful Improvement in Chair-Seats, of which the following is a specification.

Our invention is an improvement in chair seats, and the invention has for its object to provide a seat of the character specified, wherein a new and improved form of spring cushion is provided, capable of attachment to chairs of any character.

In the drawings: Figure 1 is a top plan view of the seat construction in accordance with the invention with parts broken away, Fig. 2 is a section on the line 2-2 of Fig. l, and Fig. 3 is a top plan view of the improved seat with the cover removed.

The present embodiment of the invention comprises a frame consisting of side mem bers 1, a front end member 2, and a rear end member 3, connected togetherto form an open frame of rhomboidal form, and spring mechanism is arranged within the frame. This mechanism comprises a ring 4, and a series of coil springs 5. Each of the springs 5 is provided at its ends with hooks 6 and 7, respectively, and the hooks 7 of the springs are connected with the ring 4: before mentioned.

The outer ends of the springs are anchored to the frame. members 1, 2 and 3 in such manner that the springs radiate from the ring in spaced relation, and in such manner that neither of the members 1, 2 or 3 has less than two springs connecting it to the ring.

The end members 2 and 3 are connected to the ring by two springs, while the side members 1 are connected to the ring by three springs. In the present instance, the springs are anchored to the frame by a wire 8, the said wire being passed around headed pins 9 in the frame members and through the hooks 6 of the spring.

As shown in Fig. 3, the wire passes from that pin 9 on one of the frame members 1, which is adjacent to the frame member 3 through the hook 6 of a spring, and then over a pin 9 at the adjacent end of the frame member 3, and back through the same hook 6. The wire then passes over the central pin 9 of the frame member 3, and from there to the h0ok 6 of the succeeding spring 5. This spring 5 is connected to the pin 9 at the end of the frame member 3 remote from the firstnamed pin in the same manner as it was connected to the first-named pin. The wire then passes over the first pin of the opposite member 1 adjacent to the frame member 3, and from there through the hook 6 of the third spring and to the pin 9 of this frame memher 1, which is adjacent to the frame member 2. The frame member 2 is connected to two springs in the same manner as the frame member 3, and the opposite frame member 1, that is, the first-named frame member 1 is connected to three springs in the same manner as the frame member 1, just described.

It will be noticed from an inspection of Fig. 3 that each frame member 2 and 3 has three pins 9, and were the wire 8 continuous there would be needed but two pins 9'on each of the side members 1. An additional pin 9 is provided however, for the connection of the other end of the wire 8, and this pin 9 is arranged adjacent to the firstnamed pin 9. The ends of the wire are wrapped around the adjacent pins 9 and 9.

While the above-described manner of anchoring is preferred, it will be obvious that the springs might be anchored in many different ways, the essential feature being that they be anchored in a position radial to the ring and spaced apart at equal distancesfrom each other.

A sheet 10 of burlap or like fibrous material is arranged over the springs 5,-the ring 1, and the anchoring wire 8, the edges of the sheet being secured to the upper face of the frame members 1, 2 and 3, by means of tacks 11 or the like.

A filling 12 of tow or similar material is arranged on the burlap, and the tow is held in place by a cover 13, of leather or upholstering material. Referring to Fig. 2, it will be seen that each of the frame members 1, 2 and 3 is rabbeted on its under face and at its outer edge as indicated at 14, and at the upper face each of the frame members is rounded as shown at 15. The side edges of the sheet 13 are brought over the rounded edges 15 and are lapped upon the rabbeted portion 14 of the frame members, and are secured to this portion by tacks 17 or the like.

We claim:

1. In combination an open frame radially disposed coil springs connected at their inner ends centrally oi the frame and a running connection between the outer ends of the springs and the frame bars for centralizing the springs and equalizing the tension thereon.

2. In combination an open frame, a ring disposed centrally oi the frame, radially arranged coil springs having their inner ends loosely connected With the ring and having eyes at their outer ends and a single running connection between the outer ends of the springs and the frame bars, said connection loosely engaging the eyes at the outer ends of the springs.
